2. 1. Specification of Dorsal and Intermediate Telencephalic Character

   Author : Matthew Marklund; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; telencephalon; forebrain; dorsoventral patterning; WNT; FGF; RA; retinoid-mediated signaling; development; specification; cortex; striatal; intermediate; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : The telencephalon is the most highly evolved region of the vertebrate central nervous system (CNS). The major structures of the telencephalon - the cortex and basal ganglia – derive from the dorsally positioned pallium and the ventrally positioned subpallium, respectively. READ MORE

4. 2. Microsystem technology for microwave applications at frequencies above 100 GHz

   Author : Sofia Rahiminejad; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transitions; GHz; High frequency; RF; MEMS; Gap waveguides; Waveguide;

   Abstract : The rapid development of wireless technology today shows an increasing need forelectromagnetic components operating at even higher frequencies. Higher frequencies offer wider bandwidth, higher spatial resolution and are needed for technologies such as automotive car radars, wireless media communication and body scanners. READ MORE

5. 3. Gap Waveguide Technology for Millimeter Wave Applications and Integration with Antennas

   Author : Elena Pucci; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Array Antennas.; Microstrip Lines; Micromachining; Artificial Magnetic Conductors; Millimeter Waves; Waveguide Resonators; Packaging of Microwave Components; Gap Waveguides; Losses;

   Abstract : The increasing advance of short range wireless communications requiring high data rates and the lack of available spectrum have driven researchers and industry to move towards higher frequencies, in particular to the millimeter wave range. The opening of this wide portion of free spectrum has risen a large interest in developing mm-wave communication systems for commercial applications. READ MORE

6. 4. Compact orientation and frequency estimation with applications in biometrics : Biometrics on the orientation express

   Author : Anna Mikaelyan; Josef Bigun; Kenneth Nilsson; Raffaele Cappelli; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Automatic feature extraction still remains a relevant image and signal processing problem even tough both the field and technologies are developing rapidly. Images of low quality, where it is extremely difficult to reliably process image information automatically, are of special interest. READ MORE

7. 5. Paths to improving atmospheric models across scales : The importance of the unresolved scales

   Author : Kerstin Hartung; Gunilla Svensson; Rodrigo Caballero; Olof Runborg; Heikki Järvinen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; global climate models; atmospheric blocking; topographic forcing; physical parametrizations; single-column model; atmosphere-ocean single-column model; air-sea interaction; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Correct representation of physical processes, the parametrizations, and their interaction with the resolved circulation is crucial for the performance of numerical models. Here, focus is put on understanding model biases and developing tools to alleviate existing biases. READ MORE
